Further, the top surface 224 of the lifting plate 221 is an inclined plane, and the inclined direction is consistent with the inclined direction of the inner bottom surface 211 of the trough 210, i.e. the lower end is close to the side of the baffle plate 222, so that the handle body is tightly attached to the side of the baffle plate 222 under the guiding action of the inclined top surface 224 during the lifting process of the lifting plate 221, the baffle plate 222 plays an effective role in blocking materials, and compared with the horizontal top surface, the inclined top surface 224 can effectively prevent the handle body from rolling to the other side and separating from the lifting plate 221 during the lifting process.
Further, the lifting plate 221 and the baffle plate 222 are both obliquely arranged, so that the height of the whole feeding machine is reduced, and the height and the volume of the whole sewing production line are reduced.
In addition, the supporting part of the conveying assembly 230 includes a bottom plate 235 and a buffer side plate 232 and a stopper side plate 233 respectively located at both sides of the conveying belt 231, the buffer side plate 232 is located between the striker plate 222 and the conveying belt 231, the buffer side plate 232 has an inclined buffer portion 234, the extending direction of the inclined buffer portion 234 is parallel to the conveying direction of the conveying belt 231, and the inclined direction is identical to the inclined direction of the striker plate 222; the high end of the inclined buffer part 234 is flush with and attached to the low end of the top surface 223 of the striker plate 222, and the low end is positioned above the conveyor belt 231; the extending direction of the stopper side plate 233 is parallel to the conveying direction of the conveying belt 231 and is located above the conveying belt 231. When the tubular handle body is separated from the inclined top surface 223 of the baffle plate 222 and is about to roll onto the conveying belt 231, the handle body rolls onto the inclined buffer part 234 of the buffer side plate 232, the inclined buffer part 234 plays a role in buffering the rolling of the handle body, and the rolling speed of the handle body is reduced, so that the handle body can be stopped on the conveying belt 231 as much as possible, and is conveyed to a material taking position along with the conveying belt 231; the stopper side plate 233 further plays a role of stopping the handle body rolled onto the conveyor belt 231, preventing the handle body from continuing to roll off the conveyor belt 231.
Further, the inclination angle of the inclined buffer portion 234 is smaller than the inclination angle of the top surface 223 of the striker plate 222, i.e. the slope of the inclined buffer portion 234 is gentle, and the width of the inclined buffer portion 234 is larger than the width of the top surface 223 of the striker plate 222, so as to extend the rolling path of the handle body thereon, thereby improving the buffer effect on the handle body.
For the hook connecting ring feeding machine 300, in this embodiment, a vibration disc is adopted, meanwhile, a discharge hole of the vibration disc is connected with a linear rail 310, the linear rail 310 extends to a material taking position, the linear rail 310 extends a vibration path and plays a guiding role on a hook connecting ring coming out of the discharge hole, so that the hook connecting ring can orderly move to the material taking position. In this embodiment, the hook connecting ring is a circular ring, and the linear rail 310 is configured such that the hook connecting ring rolls and conveys along the linear rail, for example, the linear rail 310 is a U-shaped rail with an opening facing to the left or right, rather than an opening facing upwards.
Because some chest expander handles can be sewn with trademarks, the trademark sewing on the chest expander handles in the prior art is completed manually, the efficiency is low, and the sewing quality is difficult to ensure. To approach this problem in the prior art, referring to fig. 2 and 5, the automated chest expander handle sewing line of the present embodiment further includes a trademark sewing unit 900, the trademark sewing unit 900 being located on the upstream side of the fixed-length slitter 100, and a trademark being sewn to the webbing before the webbing enters the fixed-length slitter 100.
Specifically, as shown in fig. 5, the trademark sewing unit 900 includes a trademark accommodating groove 910, a trademark taking device 930 and a trademark sewing device 940, where a plurality of trademarks are stacked up and down in the trademark accommodating groove 910, a webbing from the reel 800 and between the reel 800 and the fixed-length belt cutter 100, when passing through the trademark sewing position, the trademark taking device 930 takes out the trademarks in the trademark accommodating groove 910 one by one and places the trademarks on the webbing at the trademark sewing position, then the trademark sewing device 940 carries out trademark sewing, after the trademark sewing, the webbing continues to travel under the drive of the taking mechanism 400, and the trademark sewing unit 900 continues to sew the trademark at the next position on the webbing, so that the trademark is reciprocated. The groove profile of the trademark accommodating groove 910 is adapted to the trademark profile to locate the placed trademark, so that the trademark is placed in order; the trademark taking device 930 is specifically a sucker taking manipulator, and can act in multiple dimensions, so that the trademark taking and placing requirements are met, and the trademark sewing device 940 is a computer sewing machine.
Further, since a plurality of trademarks are stacked up and down in the trademark accommodating groove, the trademarks are different in position in the up-down direction, if the trademarks are not moved in the up-down direction, the material taking sucker of the trademark taking device 930 must be able to move up and down if the trademark taking device 930 can take materials smoothly, and the sucker material taking manipulator or other manipulator of this type has complex structure, high cost, and the more the movement dimension, the more potential fault points. In order to solve the technical problem, in this embodiment, the trademark taking device 930 adopts a conventional sucker taking manipulator, the taking position is fixed, a trademark jacking mechanism 920 is configured at the trademark accommodating groove 910, and the trademark jacking mechanism 920 jacks up the trademark stacked in the trademark accommodating groove 910, so that the trademark on the uppermost layer is always at the same height, so as to ensure that the trademark taking device 930 takes materials smoothly.
Specifically, the trademark jacking mechanism 920 includes a jacking driving member 921 and a trademark tray (view angle reason is not shown), the jacking driving member 921 is fixedly arranged, the trademark tray is horizontally arranged and fixedly connected to an output end of the jacking driving member 921, lifting is achieved by driving of the jacking driving member 921, meanwhile, the trademark tray stretches into the trademark accommodating groove 910, a plurality of trademarks are stacked on the trademark tray, after the uppermost trademark in the material taking position is taken away by the trademark taking device 930, the jacking driving member 921 acts to drive the trademark tray to drive the trademark to move upwards, so that the uppermost trademark reaches the material taking position at this time, and the trademark is reciprocated until the lowermost trademark is taken away, and new trademarks are stacked again.
